1 Samuel 24:14

24:14 Who has the king of Israel come out after? Who is it that you are pursuing? A dead dog? A single flea?

1 Samuel 26:20

26:20 Now don’t let my blood fall to the ground away from the Lord’s presence, for the king of Israel has gone out to look for a flea the way one looks for a partridge ¹  in the hill country.”

[26:20]  ¹ tn Heb “the calling [one],” which apparently refers to a partridge.
